ASQL*Plus

BJava

CYou cannot use .NET with ADB.

DOracle Data Access Components for Windows

Show Answer

Correct Answer: D

Oracle Data Access Components (ODAC) for Windows is a collection of software components that provide data access to Oracle databases from .NET applications.ODAC includes Oracle Data Provider for .NET (ODP.NET), which is the driver that connects to Autonomous Database from .NET applications2.ODP.NET supports both .NET Framework and .NET Core applications3.ODP.NET can be used with Visual Studio and Visual Studio Code to develop and deploy .NET applications for Autonomous Database45.Reference:

Question No. 2

Which statement is FALSE about the Catalog tool?

AYou can view the data definition of an entity.

BImpact shows the entities that depend on the source.

CYou can delete an entity from the Autonomous Database via the Catalog tool.

DYou can limit the display of entities to only those with certain names, schemas, types, or applications by entering values in the Search field.

Show Answer

Correct Answer: C

The Catalog tool is a built-in feature of Autonomous Database that provides an easily searchable inventory of all the objects in, or accessible from, the database, such as schemas, tables, views, columns, analytic views, files on cloud object storage, and more1. However, the Catalog tool does not allow you to delete any entity from the database.You can only view the details, lineage, and impact of an entity using the Catalog tool2.To delete an entity from the database, you need to use other tools such as SQL Developer Web or APEX3.Reference:

Question No. 3

Which two actions can you perform with Autonomous Data Guard enabled on Autonomous Database on Shared Infrastructure?

ASwitchover

BReinstate

CChange Protection Mode

DView Apply Lag

EFailover

Show Answer

Correct Answer: A, E

Autonomous Data Guard is a feature of Autonomous Database on Shared Infrastructure that provides data protection and disaster recovery for your database by creating and maintaining a standby database that continuously gets updated with the changes from the primary database4. With Autonomous Data Guard enabled, you can perform a switchover or a failover operation to switch roles between the primary and standby databases.A switchover is a planned role reversal that does not affect availability5.A failover is an unplanned role reversal that occurs when the primary database becomes unavailable due to a failure or disaster6.You cannot perform a reinstate operation, which is used to re-synchronize a disabled standby database with the primary database after a failover7.You also cannot change the protection mode, which determines how redo data is transmitted from the primary database to the standby database4.You can only view the apply lag, which is the difference between the redo applied on the standby database and the redo generated on the primary database5.Reference:

Question No. 4

Which index type is designed to index catalog information?

ACONTEXT

BCTXCAT

CCTXRULE

DCONTAINS

Show Answer

Correct Answer: B

CTXCAT is an index type that is designed to index catalog information such as product names, prices, descriptions, etc.CTXCAT indexes are suitable for e-commerce applications where users can query on multiple attributes of a product8. CTXCAT indexes are faster to create and maintain than CONTEXT indexes, which are designed to index large amounts of text such as documents, web pages, etc.CTXCAT indexes also support mixed queries that combine structured and unstructured predicates9.CTXRULE is an index type that is designed to index a set of queries or rules that can be evaluated against documents or rows in a table10.CONTAINS is not an index type, but a SQL operator that performs text searches on CONTEXT and CTXRULE indexes11.Reference:

Question No. 5

What can you do with graphs? (Choose two)

AFind patterns that are anomalous and use that to detect fraud.

B3-D modeling

CProduct recommendations

DFacial recognition

Show Answer

Correct Answer: A

Graphs are data structures that represent the connections and relationships between entities, such as people, products, places, etc.Graphs can be used to perform various types of analysis based on these connections, such as finding patterns that are anomalous and use that to detect fraud1or generating product recommendations based on the preferences and behaviors of similar customers2.3-D modeling and facial recognition are not applications of graphs, but rather of other types of data analysis techniques, such as computer graphics and machine learning34.Reference:
